What is it?

get-audio-metadata.py is a python script to analyze a folder full of wav files and generate a CSV report containing various metadata including:

• filename
• file length (in bytes)
• format
• bit depth
• bitrate
• number of channels
• sample rate (in Hz)
• duration (in seconds)
• file path
• onsets (i.e. offset from beginning of file)
• loudness (LKFS i.e. LUFS with K-Weighting)

It will generate a file called audio-metadata-output.csv in the specified output folder. It should run on Windows, Mac or Linux (or theoretically any platform that can run python 3).

Install

• install latest python 3 (https://python.org)
• unzip contents into a folder
• navigate to that folder and install requirements (see below)

Windows:

py -3 -m pip install -r requirements.txt

or run install.bat

Mac:

pip3 install -r requirements.txt

or run install.sh

Usage

usage: get-audio-metadata.py [-h] --input-dir [INPUT_DIR] [--output-dir [OUTPUT_DIR]]

options:
  -h, --help            show this help message and exit
  --input-dir [INPUT_DIR]
                        Directory containing files to analyze
  --output-dir [OUTPUT_DIR]
                        Directory into which to generate CSV report

If you don't supply an input folder or output folder at the command line, you'll be prompted with a dialog box to select the folders.

Examples

Directly via python:

py get-audio-metadata.py --input-dir C:\path\to\audio\files --output-dir D:\output

With helper batch file:

.\get-audio-metadata.bat  C:\path\to\audio\files D:\
